VNC viewer connection closed unexpectedly

[mvperez]

Hi @mvberg , I'm encountering an issue to view the IB from VNC. But this problem only appears in windows. I tried several vnc viewer such as tightvnc, tigervnc, and realvnc. In MacOS I just use tightvnc and it's working fine. Here is an error I got in realvnc connecting to localhost:5901. Have you encountered this problem in Windows?

Update: I noticed the some errors on docker-compose up --build

add this into tws Dockerfile RUN sed -i -e 's/\r$//' runscript.sh RUN sed -i -e 's/\r$//' /usr/bin/xvfb-daemon-run RUN sed -i -e 's/\r$//' /etc/init.d/xvfb RUN sed -i -e 's/\r$//' /etc/init.d/vnc RUN sed -i -e 's/\r$//' /root/Jts/jts.ini RUN sed -i -e 's/\r$//' /root/IBController/IBController.ini

Hi @jeffreymurdock , Thanks for that. I also added these two lines to add jts.ini and IBController.ini

ADD ./ib/jts.ini /root/Jts/jts.ini ADD ./ib/IBController.ini /root/IBController/IBController.ini

Save my Dockerfile and run "docker-compose up --build" again. It seems to start properly the container. But when I view TWS in VNC it seems the gateway connection repeatedly restarting (disconnected/connected status).

Here's my full Dockerfile

1. hm, never had that on Windows - checking ...
2. are you using the e-demo credentials for IB or an actual login?

[mvperez]

Nope. I'm using another account which is working fine in mac.

UPDATE: I think I found possible root cause here. I've learned you can't login same account at the same time. One will automatically logout. I will confirm it when I get into the machine and update this issue again.
